How to Use the Heading Analyzer
Simply paste your HTML content into the textarea above and click "Analyze Heading Structure." The tool will parse your HTML and examine all heading tags (H1 through H6), checking for proper hierarchy, duplicate headings, skipped levels, and other SEO issues. You'll receive a quality score and a detailed breakdown of any problems found.
What This Tool Checks
- H1-H6 Count: Shows how many headings of each level exist in your HTML
- Hierarchy Tree: Visual indented tree showing the structure of your headings
- Missing H1: Your page should have exactly one H1 tag
- Multiple H1 Tags: Google recommends one H1 per page
- Skipped Levels: Detects when heading levels jump (e.g., H1 → H3 without H2)
- Empty Headings: Flags headings with no text content
- Duplicate Headings: Identifies identical heading text
- Long Headings: Flags headings over 70 characters that may not display well
Why Heading Structure Matters for SEO
Proper heading hierarchy is crucial for search engine optimization. Search engines use heading tags to understand page structure and determine the main topics covered. A well-organized heading structure helps Google understand your content, improves user experience, and can boost your rankings. The H1 tag should describe the main topic, H2 tags should outline major sections, and H3-H6 should provide deeper structure as needed.
Best Practices for Heading Tags
- Use exactly one H1 per page that describes the main topic
- Follow a logical hierarchy (H1 → H2 → H3) without skipping levels
- Keep headings descriptive and concise (under 70 characters)
- Include your target keywords naturally in headings
- Use headings to organize content, not for styling
- Never use headings just for visual effect; use CSS instead
Frequently Asked Questions
Can I paste HTML with inline styles and attributes?
Yes! The analyzer only extracts heading tags and their text content. All other HTML attributes and styles are ignored during analysis.
What counts as a "skipped level"?
A skipped level occurs when you jump from H1 to H3 without having an H2 in between, or from H2 to H4 without H3. This breaks the logical hierarchy and confuses search engines.
Is it bad to have multiple H2 tags?
No, multiple H2 tags are fine and often necessary for organizing different sections. Only the H1 tag should appear once per page.
How is the quality score calculated?
The score is based on the severity and count of issues found. A perfect page with one H1, proper hierarchy, and no duplicates scores 100. Each issue reduces the score proportionally.
Does this tool analyze my live website?
No, this is a client-side tool that only analyzes the HTML you paste directly. For analyzing a live website's headings, use your browser's Inspector (F12) to view the page source and copy-paste the HTML here.
